Gaga said she bought the items in the spirit of preservation, tweeting, "The 55 pieces I collected today will be archived & expertly cared for in the spirit & love of Michael Jackson, his bravery, & fans worldwide."

An auctioneer said the jacket that Jackson wore on the Bad tour brought $240,000, while a pair of crystal-encrusted gloves sold for more than $100,000 each. The auction, featuring items from the collection of Jackson's longtime costume designers, Dennis Tompkins and Michael Bush, raised more than $5 million. Some proceeds will benefit Guide Dogs of America and Nathan Adelson Hospice of Las Vegas.
